Officials say nine civilians were killed as Pakistani and Indian troops bombarded each another with gunfire and mortar shells across the border in the disputed region of Kashmir.

Indian civilian administrator Shantmanu says tens of thousands of villagers were fleeing homes Monday on the Indian side of what's widely recognized as an international border between the two countries.

Each side accused the other of firing first, saying its troops only retaliated. India and Pakistan have each controlled a part of Kashmir since 1947, though both claim the region in its entirety.

Shantmanu, who uses one name, said villagers were being evacuated to nearby government shelters. He said 35 people were injured on the Indian side, while the Pakistani army said three were injured on its side.
